VMAX, VMIN, VPMAX, and VPMIN

VMAX (Vector Maximum) compares corresponding elements in two vectors, and copies the larger of each pair into the corresponding element in the destination vector.

VMIN (Vector Minimum) compares corresponding elements in two vectors, and copies the smaller of each pair into the corresponding element in the destination vector.

VPMAX (Vector Pairwise Maximum) compares adjacent pairs of elements in two vectors, and copies the larger of each pair into the corresponding element in the destination vector. Operands and results must be doubleword vectors.

VPMIN (Vector Pairwise Minimum) compares adjacent pairs of elements in two vectors, and copies the smaller of each pair into the corresponding element in the destination vector. Operands and results must be doubleword vectors.

Show/hideSyntax

Vop{cond}.datatype Qd, Qn, Qm
Vop{cond}.datatype Dd, Dn, Dm
VPop{cond}.datatype Dd, Dn, Dm

where:

op

must be either MAX or MIN.

cond

is an optional condition code.

datatype

must be one of S8, S16, S32, U8, U16, U32, or F32.

Qd, Qn, Qm

are the destination vector, the first operand vector, and the second operand vector, for a quadword operation.

Dd, Dn, Dm

are the destination vector, the first operand vector, and the second operand vector, for a doubleword operation.

Show/hideFloating-point maximum and minimum

max(+0.0, -0.0) = +0.0.

min(+0.0, -0.0) = -0.0

If any input is a NaN, the corresponding result element is the default NaN.
